If you're like many people, you may periodically receive email attachments in Microsoft PowerPoint's PPS format. This format efficiently conveys ideas via a combination of graphics, sounds and animation. To extract JPG files from a PowerPoint presentation, you can select individual images and save them as JPG files. You can also save the entire presentation or selected slides in JPG format, which will convert the slides. However, this format removes all multimedia elements and leaves only the static images.

Saving Individual JPGs

Open the PPS file in Microsoft PowerPoint.

Right-click the JPG image you wish to extract and select "Save As Picture."

Click the "Save As Type" drop-down menu and select "JPEG File Interchange Format" if it is not already selected.

Click "Save."

Saving Slides as JPGs

Open Microsoft PowerPoint.

Hold the "Ctrl" key and press "O." Select the PPS file you wish to convert from the Open dialog window.
